Hence, the NMI function will always be there, but it may not be connected to external pin / peripherals.</SPAN><BR /><BR /><SPAN>"The NMI is not implemented on the LPC111x/LPC11Cxx" should be interpreted as cannot be used to generate interrupt from peripherals or pin. But, of course, it could be used for software interrupt without any restriction.</SPAN><BR /><BR /><SPAN>FYI also, the LPC1100XL series and LPC11Uxx series implement NMI (as in you can connect the NMI to other peripherals / GPIO pin interrupt).</SPAN></BODY></HTML> Wed, 15 Jun 2016 19:35:17 GMT https://community.nxp.com/t5/LPC-Microcontrollers/NMI-support/m-p/535169#M10956 lpcware 2016-06-15T19:35:17Z
